וַאֲכַלְתֶּם־שָׁ֗ם לִפְנֵי֙ יְהוָ֣ה אֱלֹֽהֵיכֶ֔ם וּשְׂמַחְתֶּ֗ם בְּכֹל֙ מִשְׁלַ֣ח יֶדְכֶ֔ם אַתֶּ֖ם וּבָתֵּיכֶ֑ם אֲשֶׁ֥ר בֵּֽרַכְךָ֖ יְהוָ֥ה אֱלֹהֶֽיךָ׃
Y comeréis allí delante de SEÑOR vuestro Dios, y os alegraréis, vosotros y vuestras familias, en toda obra de vuestras manos en que SEÑOR tu Dios te hubiere bendecido.
